The World TeamTennis Pro League today announced the League has added a franchise in Washington, D.C.

The 2008 WTT regular season runs July 3 -23 with the WTT Championship Weekend set for July 24-27 in Roseville, Calif. World TeamTennis, co-founded in 1974 by tennis legend Billie Jean King, features several generations of tennis pros competing in a co-ed pro league in communities throughout the U.S. each summer. This is the first Washington, D.C.-based team in the League's 33-year history. "Washington D.C. is a world-class sports market that will be a showcase for World TeamTennis," said WTT CEO/Commissioner Ilana Kloss. "We've looked at this market for several years as a great location for expansion. Thanks to the leadership and vision of Mark Ein, everything came together for it to happen this year." "Area fans have supported tennis for many years and we think they will really embrace our unique brand of tennis," added Kloss. The Kastles will select their lineup when they draft sixth out of 11 teams at the WTT Player Draft on April 1 in Miami. Washington will play seven home matches and seven matches on the road during the month-long season. The team is currently looking at several potential locations to build a temporary stadium for the season. Ein, a native of Washington and a seasoned, successful entrepreneur and investor is excited to combine his business interests and commitment to the community with the sport of tennis. "I am thrilled to bring World TeamTennis to our area. WTT tennis is great entertainment emphasizing fan interaction, and it is the only major sport with men and women playing together on the same team. The Washington Kastles season will be an exciting summertime addition to our local economy and a fun activity for our entire community."
